Embodiment
Fig. 1 shows the selected portion of the example flow battery (flow battery) 20 for optionally storing and discharge electric energy.As an example, flow battery 20 can be for converting the electric energy generating to chemical energy in rechargeable energy system, and it can be stored until the later time now exists the demand to electric energy.Then flow battery 20 can convert chemical energy to electric energy, to be supplied to for example electrical network.As will be described, flow battery 20 comprises for strengthening the property and the feature of durability.
Flow battery 20 comprises liquid electrolyte 22, and it has electroactive substance (specie) 24, and it brings into play function redox centering with respect to additional liquid electrolyte 26 and electroactive substance 30.For example, electroactive substance is based on vanadium, bromine, iron, chromium, zinc, cerium, lead or its combination.In an embodiment, liquid electrolyte 22 and 26 can be moisture or anhydrous solution, and it comprises one or more in electroactive substance.
Liquid electrolyte 22 and 26 is accommodated in corresponding storage tank 32 and 34.As shown in the figure, storage tank 32 and 34 is the cylindrical storage tank being equal to substantially; But storage tank 32 and 34 alternately has other shape and size.
Liquid electrolyte 22 and 26 is transferred (for example, pumping) to one or more battery units 36 by corresponding supply line 38, and turns back to storage tank 32 and 34 from one or more battery units 36 via the line of return 40.
In operation, liquid electrolyte 22 and 26 is transported to battery unit 36, to convert electric energy to chemical energy, or converts chemical energy to electric energy, and it can be released.Electric energy is transmitted to and from battery unit 36 by power path 42, described power path 42 completing circuits, and allow completing of electrochemical redox reaction.
Fig. 2 shows the example of battery unit 36.Should be understood that: flow battery 20 can comprise the multiple battery units 36 in duplexer, depend on the design capacity of flow battery 20.As shown in the figure, battery unit 36 comprise first-class field plate 50 and with the isolated second field plate 52 of first-class field plate 50.Second field plate 52 can roughly be similar to first-class field plate 50, as will be described below.
First-class field plate 50 comprises the first flow field channel 54 and the second flow field channel 56, and it separates with the first flow field channel 54 by rib shape portion 58.Flow field channel 54 and 56 is arranged to exist flow path 60 to flow through the rib shape portion 58 between passage 54 and 56 for liquid electrolyte 22 or 26.
The first and second electrodes 62 and 64 are configured to, adjacent to corresponding the first and second flow-field plate 50 and 52, make the liquid electrolyte 22 or 26 that flows through rib shape portion 58 must flow through corresponding electrode 62 or 64.In this example, ion exchange membrane sheet 66 is configured between electrode 62 and 64.
In the embodiment shown, the one or both in electrode 62 and 64 comprises carbon paper (carbon paper) 68, and such as carbon fiber paper, it is catalytic activitys with respect to liquid electrolyte 22 and/or 26.That is to say, the surface of the material with carbon element of carbon paper is as the catalytically active surface in flow battery 20.In the redox reaction of flow battery 20, relatively low for the energy barrier of reaction, thus more expensive catalysis material, such as noble metal or alloy etc., is unwanted, as adopted the battery unit of gas reactant.In one embodiment, activate carbon paper 68 by Technology for Heating Processing, clearing up material with carbon element, increase surface area, and produce the oxide as active catalytic position.In an embodiment again, carbon paper is carbon/carbon compound material, and it comprises carbon fiber and carbon adhesive residue.Polyacrylonitrile (Polyacrolynitrile) is an example precursor of the carbon fiber for using at carbon paper 68.Phenolic resins is an example precursor for carbon binding agent.
In flow battery, between the pressure drop of the fluid of the liquid electrolyte by battery unit and performance, exist compromise.For example, not adopting flow field and force liquid electrolyte to flow through in the flow battery of carbon felt electrode (" flowing through "), there is performance relatively preferably, but high pressure drop (the more input of its needs energy moves electrolyte and passes through battery unit), and relatively low durability, reason is the stacked compression on ion exchange membrane sheet and carbon felt.Adopting flow field (, " flow walk around ") flow battery in, there is pressure drop still less pass through electrode because liquid electrolyte is not forced to, but performance is relatively low, because not existing for the enhancing quality of passing through electrode being provided by convective flow is delivered in considerable.
Flow battery 20 adopts " mixed flow " flow field and carbon paper 68 that useful balance is provided between pressure drop and performance.Term " mixed flow " refers to the combination of " flowing through " and " flow and walk around ".In an embodiment, " mixed flow " realized in the following manner: flow field channel 54 and 56 is configured in to (and alternatively also on second field plate 52) on first-class field plate 50.For example, the second flow field channel 56 is in the downstream of the first flow field channel 54, therefore the liquid electrolyte 22/26 in the second flow field channel 56 due to the pressure loss compared with liquid electrolyte 22/26 in the first flow field channel 54 in lower pressure.The difference of pressure is build-up of pressure gradient between passage 54 and 56, and it drives the rib shape portion 58 that at least a portion of liquid electrolyte 22/26 flows through flow path 60 from the first flow field channel 54 to enter in the second flow field channel 56.In several examples, flow field channel 54 and 56 is passages of following configuration: the configuration of serpentine shape passage, the passage that crosses one another configure, the passage that partly crosses one another configures or its combination, so that barometric gradient to be provided.
Select the characteristic of carbon paper 68 according to " mixed flow " design of passage 54 and 56, to strengthen the property and durability.For example, carbon paper 68 has and in the time of the compression stress of 0.8MPa, is less than 20% predetermined compression strain, not porosity and the thickness (t) in scope 150～400 μ m (micron) by compression in scope 60-85%.Young's modulus that can specified compression, instead of compression strain, prerequisite is that stress strain response is linear.By contrast, the carbon felt conventionally using in flow battery is relatively soft, and in can invasive channel, flows and cause inconsistent performance to limit.Relatively hard carbon paper 68 reduces invades, thereby reduces flow restriction and increase consistency of performance.Carbon felt is also relatively thick, and increases duplexer size and ion and must move to reach the average distance of ion exchange membrane sheet.Relatively thin carbon paper 68 reduces the average distance of duplexer size and ion motion.In addition, carbon paper 68 compressibility compared with felt is lower, thereby does not need high duplexer compression, and it improves duplexer durability.In addition, carbon felt is compressed on rib shape portion, thereby has inconsistent porosity, and its Interference Flow distributes.Carbon paper 68 is relatively not too compressible, thereby compression and flow distribution are more uniformly provided.
Predetermined compressive strength, thickness (t) and not by compression porosity allow the mixed flow of liquid electrolyte 22 or 26 by the forced flow component of the rib shape portion 58 between passage 54 and 56.For example, compressive strength is greater than 0.8MPa in the time of 20% compression strain, and porosity is not 65-85vol% by compression, and thickness is 150-400 micron.In an example again, compressive strength is greater than 0.8MPa in the time of 10% compression strain, and thickness is 150-250 micron.
Fig. 3 shows the part for another example of the carbon paper 168 of flow battery 20.In the disclosure, like reference numerals is suitably marking out like in situation, and add 100 or the Reference numeral of its multiple mark out the element of amendment, it is interpreted as the same characteristic features and the benefit that comprise counter element.In this example, carbon paper 168 comprises catalytic activity carbon fiber 170.Carbon fiber 170 is by randomly or be pattern and configure, and described pattern is such as weaving structure.Carbon particle 172 is arranged on carbon fiber 170.The catalytic activity of the surface area that carbon particle 172 increases carbon paper 168 for strengthening.In one example, carbon particle 172 has the average diameter of 10-100 nanometer, and carbon paper 168 comprises the carbon particle 172 of 1-10wt%.
Carbon particle 172 can substantially distribute equably and spread all over carbon paper 168, makes carbon paper 168 have porosity relatively uniformly.Alternatively, as shown in the figure, there is the concentration gradient 174 of carbon particle 172 in the thickness (t) that runs through carbon paper 168, makes carbon paper 168 have the porosity of gradual change.In this example, concentration is as with the function of the distance of the diaphragm side of carbon paper 168 and reduce.Concentration gradient 174 allows the mobile more greatly of the liquid electrolyte 22/26 adjacent with the flow-field plate side of carbon paper 168, and the catalytic activity of the increase adjacent with the diaphragm side of carbon paper 168, to reduce the average distance of ion motion with respect to ion exchange membrane sheet 66.
In an embodiment, the liquid suspension of carbon particle 172 use carbon particles 172 in carrier fluid deposits on carbon fiber 170.Liquid suspension is applied to carbon paper 168, such as by spraying or flooding or brush, is then dried to remove carrier fluid, and carbon particle 172 is retained in carbon paper 168.Can repeat to apply and drying process, to realize the required load level of carbon particle 172.In addition, vacuum can apply and/or drying process during be applied to a side of carbon paper 168, to realize concentration gradient 174.
Fig. 4 shows the part for another example of the carbon paper 268 of flow battery 20.In this example, carbon paper 268 comprises catalytic activity carbon fiber 170 and is arranged on the carbon particle 272 on carbon fiber 170.Carbon particle 272 has multi-modal distribution of sizes, with further enhanced activity and control porosity and conductivity.In this example, carbon particle 272 comprises the carbon particle 272a with the first average diameter and the carbon particle 272b with the second average diameter that is greater than the first average diameter.In other examples, carbon particle can be in other side difference, such as microstructure and/or composition.For example, one can have two particles, and it has identical diameter, but very different density and mark and the size of micropore.
